ClNDER-ESCAPE PIPE FOR LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent No. 243,805, dated July 5, 1881.

Application filed February 23, 1881.

To all whom it may concern Be it known that I, JOSEPH SHAW, a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana,

have invented a new and useful Cinder-Escape I Pipe for Locomotives, of which the following is a specification.

My invention relates to improvements in cinder-escape pipes for locomotives, which allow IO the cinders to escape through a pipe which is placed between the two exhaust-pipes (in front of the fines) and extends down under the boiler; and the objects of my improvements are, first, to arrange a simple device that will keep the end of the boiler from filling up with large. cinders; second, to construct a cinder-escape pipe that the draft cannot pass through; third, to construct a device that will work automatically by the pressure of the cinders and jar of the locomotive. I attain these objects by the mechanism illustrated in the accompanyings, in Which Figure l is a side view of the front end of a locomotive-boiler, showing a sectional view of my device and the parts to which it is connected. Fig. 2 is an end view of the front end of a boiler, showing that my device is placed between the two exhaust-pipes. Fig. 3 is a side view of the front end ofa boiler made especially for my device, showing that in making a new boiler-front no pipe is necessary, and that the lid can be attached and operate the same as shown at Fig. 1. Fig. 418 a view of my device, showing the lid open and an end view of the same.

Similar letters refer to similar parts through- I out the several views.

a is the escape-pipe, consisting of a short piece of metallic pipe having threads cut on each ofits exterior ends. To one of the said ends is attached a short curved joint, I), (or the two joints may be made one and be the same shape.) To one end of the said joint b the rim d is secured and held in place by the bolt 6, as shown at Fig. 4. The rim consists of a flat (No model.)

piece of metal bent around the end of the said joint b, and by tightening the bolt 6 it is held firm in its place.

As thus constructed this device is complete, and can be attached to a boiler in the following manner: Drill a hole through the base of the boiler front, between thetwoexhaust-pipes, or in anyother more suitable place, and fasten solidly the end of the pipe at by threads, or in any manner that will-hold it solidly in place.

Heretofore boilers have been constructed without any such device, and when the large cinders come through the flues of the boiler they fall down and pile up around the exhaustpipes, and the exhaust is continually blowing 6o them up against the spark-arrester until they are broken fine enough to pass through it. The time and trouble of cleaning out the front of a boiler and repairing the spark-arrester renders my device practical, and when it is inserted in 6 proper place in a boiler the large cinders fall down on the base, as shown at Fig. 1. The jar of the engine when moving causes them to find their way into the pipe at, through which they fall and lodge in the joint b. During their delay in this joint the fire in them becomes extinct, and finally they work their way to the end of the joint, out of which they fall to the ground.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is

1. In a locomotive-boiler, the detachable curved pipe a, provided with a hinged lid, 0, arranged to seat on an inclined seat, in combi- 8o nation with the smoke-arch, substantially as specified.

2. Ina locomotive-boiler, the inclined bottom of a smoke-arch, in combination with an outlet-pipe provided with a lid hinged and inclined, as and for the purpose set forth.

JOSEPH SHAW.
